Product details
Overview
LT6203HMS8#TRPBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail input/output, ultralow-noise operational amplifier optimized for precision signal conditioning in high-temperature environments. It delivers 1.9nV/√Hz input voltage noise at 100kHz, 100MHz gain bandwidth, and 25V/µs slew rate while drawing only 3.3mA per amplifier at 5V supply, operating across –40°C to 125°C.
For engineers reviewing the LT6203HMS8#TRPBF datasheet, LT6203HMS8#TRPBF pinout, LT6203HMS8#TRPBF application, or LT6203HMS8#TRPBF equivalent, this device is selected for low-noise, wide-supply-range analog front-ends in battery-backed instrumentation, DSL receivers, and industrial sensor interfaces where thermal stability and rail-to-rail swing are critical.
Technical Context
The LT6203HMS8#TRPBF integrates two fully independent, unity-gain-stable amplifiers with matched input offset voltage (≤1.3mV), common-mode input range extending to both rails, and output swing within 6mV of V– and 55mV of V+ at 5V supply under load. Its architecture supports operation from 2.5V to 12.6V single-supply or ±1.25V to ±5V dual-supply configurations.
It achieves –80dBc harmonic distortion at 1MHz and maintains ≥80dB CMRR over its full temperature range, enabling high-fidelity signal acquisition in noisy industrial environments. The MSOP-8 package provides thermal resistance θJA = 250°C/W, validated for continuous operation up to 125°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6203IMS8#TRPBF | Same architecture and pinout, but rated for –40°C to 85°C only; lower max supply current (3.1mA vs 3.3mA) and reduced GBW (87MHz vs 100MHz) at 125°C. | Not suitable for extended-temperature industrial or automotive under-hood use; acceptable for commercial-grade instrumentation. | Select LT6203IMS8#TRPBF only when ambient temperature remains ≤85°C and full 100MHz bandwidth is not required. |
| ADA4898-2ARMZ | Higher noise (2.9nV/√Hz), higher supply current (10.5mA), wider supply range (±5V to ±15V), but superior DC accuracy (0.1mV VOS) and lower distortion (–105dBc). | Better suited for ultra-low-distortion audio or precision DC-coupled systems; less optimal for battery-constrained, high-temp applications. | Choose ADA4898-2ARMZ when ultra-low THD and DC precision outweigh power and thermal constraints. |
Compared with LT6203IMS8#TRPBF, the LT6203HMS8#TRPBF guarantees full specification compliance at 125°C and retains 100MHz bandwidth - essential for high-temperature signal fidelity. Against ADA4898-2ARMZ, it trades some DC precision for half the supply current and superior thermal robustness, making it optimal for embedded industrial front-ends.

FAQ
What is the maximum supply voltage for LT6203HMS8#TRPBF?
The LT6203HMS8#TRPBF supports a total supply voltage range of 2.5V to 12.6V for single-supply operation, or ±1.25V to ±5V for dual-supply configurations. Absolute maximum ratings specify 12.6V between V+ and V– terminals; exceeding this risks permanent damage. Operation at 12.6V is validated across the full –40°C to 125°C temperature range.
Does LT6203HMS8#TRPBF support rail-to-rail input and output simultaneously?
Yes, the LT6203HMS8#TRPBF supports rail-to-rail input common-mode voltage (including both V– and V+) and rail-to-rail output swing (within 6mV of V– and 55mV of V+ at 5V supply, 15mA load). This allows direct interface with unbuffered references, current-sense elements, and low-voltage ADCs without external level-shifting circuitry.
What is the guaranteed noise performance of LT6203HMS8#TRPBF over temperature?
The LT6203HMS8#TRPBF guarantees 1.9nV/√Hz input voltage noise density at 100kHz across its full operating temperature range of –40°C to 125°C. This value is specified in the Electrical Characteristics table under the "l" notation for the –40°C to 125°C grade and confirmed in typical performance curves showing stable noise behavior versus temperature.
Can LT6203HMS8#TRPBF drive a 100Ω load effectively?
Yes, the LT6203HMS8#TRPBF delivers ±15mA minimum output current and maintains rail-to-rail swing into 100Ω loads at 5V supply. At ISOURCE = 15mA, VOH is specified at 370mV below V+; at ISINK = 15mA, VOL is 210mV above V– - sufficient for driving transmission lines, active filters, or ADC input buffers with minimal headroom loss.
How does the LT6203HMS8#TRPBF differ from the LT6203CDD#TRPBF variant?
The LT6203HMS8#TRPBF uses an 8-lead MSOP package and is rated for –40°C to 125°C operation, while the LT6203CDD#TRPBF uses a 3mm × 3mm DFN package and is rated only for 0°C to 70°C. Both share identical electrical specifications at 25°C, but the H-grade ensures full parameter compliance - including GBW, noise, and distortion - at 125°C, unlike the C-grade which is not characterized beyond 70°C.
